| 靶点详情: | 蛋白酪氨酸磷酸酶受体型 M(PTPRM)是蛋白酪氨酸磷酸酶(PTP)家族的重要成员,作为跨膜受体蛋白,其结构包含胞外段、跨膜区和胞内催化结构域。PTPRM 通过可逆性磷酸化调控细胞内信号转导通路,在胚胎发育、细胞粘附、迁移和增殖等生理过程中发挥关键作用。研究表明,PTPRM 基因的异常表达与多种肿瘤的发生发展密切相关,其表达缺失或功能失调可导致细胞周期失控、侵袭能力增强及血管生成异常。此外,PTPRM 还参与神经突触的形成与重塑,在神经系统发育和神经退行性疾病中具有潜在调控功能。因其在疾病病理机制中的重要地位,PTPRM 已成为肿瘤标志物筛查、靶向治疗及神经疾病研究的热门靶点。 |
